Keyword Based Classifier Trainer


Incorporates a keyword-based document classification algorithm, targeting classification for files that have repeatable titles.

Enhances the training set to be used for classification, by writing learning data in a specified file.

This activity can only be used together with the Train Classifiers Scope activity.


  • DisplayName - The display name of the activity.
  • LearningFilePath - The full path to the file containing the classifier data. The information is retrieved from the specified path, processed and updated. This field supports only strings and String variables.
  • LearningData - The string containing the serialized classifier data. Within the same string, the information is read, processed, and updated. This field supports only strings and String variables.


    Only one of the parameters can be set. You can use either the LearningData string or the LearningFilePath string.

    The LearningFilePath specifies the locations from where to retrieve the classifier data while the LearningData contains the actual information of that classifier.

  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

    Note: The best practice is to create an empty .json file at that location, then use its name in the LearningFilePath field.
